Trang 1Designation: D4995−10 (Reapproved 2015)
Standard Specification for
Electronic and Degreasing Grades of 1,1,2–Trichloro
1,2,2,–Trifluoroethane Solvent1
This standard is issued under the fixed designation D4995; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision A number in parentheses indicates the year of last reapproval A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1 Scope
1.1 This specification establishes the requirements for three
grades of trichlorotrifluoroethane solvent:
1.1.1 Type I electronic or ultra-clean grade,
1.1.2 Type II standard or vapor-degreasing grade, and
1.1.3 Type IIA general purpose, packaged in a pressurized
container grade
1.2 The values stated in SI units are to be regarded as
standard No other units of measurement are included in this
standard
1.3 This standard does not purport to address all of the
safety concerns, if any, associated with its use It is the
responsibility of the user of this standard to establish
appro-priate safety and health practices and determine the
applica-bility of regulatory limitations prior to use.

3 Classification
3.1 Type I—Type I solvent is intended for use in the cleaning
of space vehicle components, precision assemblies, oxygen systems and electronic equipment by the processes of spraying, flushing, vapor degreasing, or ultrasonics The solvent is especially applicable for cleaning precision parts and assem-blies in clean rooms and for use as a medium in testing the cleanliness of components that are assumed to be clean
3.2 Types II and IIA—Types II and IIA are typically used in
vapor degreasing applications or in other processes where the requirements for purity and cleanliness are less stringent than those of a cleaning process using Type I solvent
4 Properties
4.1 Electronic or ultra-clean and degreasing grades of trichlorotrifluoroethane shall conform to the requirements pre-scribed inTable 1

Halogenated Organic Solvents and Fire Extinguishing Agents and is the direct
responsibility of Subcommittee D26.03 on Cold Cleaning.
